IMPROVEMENT IN WINDMILLS.

The Schedule. referred to in these Letten Patent and making pan: of the lune.

To all whom it may concern Be ist known that I, CHARLES GOODWIN, of Boardstown, 1n the county oi' Cass, and State of Illinois, have invented a. new anduseiul Improvement in NVindmills;

A and I do hereby declare that the following is a full, clear,

and exact description thereof, which will enable others skilledm the art to makeand use the saine, reference being had to the accompanying drawings, forming part 'of this specification.

My invention relates tp Vimprove-ments in windmills, whereby it is designed to provide a, more simple and eci'ent apparatus than those now in use; and it consists in the arrangement of parts, as will be described.

Figure 1 represents a. plan view of my improved windmill;

in a groove therein. The said swinging fra-ine supports the horizontal shaft D of the wind-wheel, in bearings on the top ofthe same. Upon the top of the bearings of the said shaft is arranged a vane, F, at a slight ongle to the shaft, and with reference tothe wind-wheel, so that the pressure of the wind on the side of the vane will be vin the right directionto'countract the tendency wheel around sideways tothe wind.vl

G represents the whirl-wheel, which is attached to theshaft in alnanner to receive the air from the directail-board or vane for regulating the position oi' the wheel witlrrefcrence to the wind is necessary.

to admit of their swinging thereon, andere provided on their narrow sides with the Iwire springs K, .which allow them to open when the wind blows hard, and which closes them the wind subsides, swinging thereby, to regulate the motion of the wheel, as the wind changes.

ring d oi' the traine oi' the wheel, are provided with friction-rollers, and the out-er ends soldered or otherwise fastened to the wings H. l Ido not elaiin the use of spiral springs, as I amaware that they are not new, and I consider the agrposition upon. the shaft D, and Operating in connection with the wheel G, as herein described forithe purpose speciiied. v
